Neatline Time Not working

I have installed Neatline Time plugin and added a time line. Not sure where that timeline is then suppose to appear so I clicked on "Edit Item Query" and I get this error:
Catchable fatal error: Argument 1 passed to item_search_filters() must be an array, boolean given, called in /home/content/51/9193051/html/theredwoodhouse.org/plugins/NeatlineTime/views/admin/timelines/query.php on line 17 and defined in /home/content/51/9193051/html/theredwoodhouse.org/application/libraries/globals.php on line 1990
